It's not just Moog that has the pivot pin problem. I've got some ACDelco that Rock Auto wouldn't warranty with the same problem. I don't know how many actual manufacturers there are anymore compared to brand names.
I went through an issue with a Comp Cams kit (yeah, I know about the current problems). Lifters were LOOSE in the block (440). So, I measured the diameter and figured out they were Ford lifters. Called summit and they sent a second set of Comp Mopar lifters. Yup. Ford lifters again. I asked if they would swap to another similarly priced brand lifter. They agreed and sent me Crane lifters. No question in my mind that they came out of the SAME plant. The box was an identical size with identical size labels and fonts and layout. But, the Crane's were Mopar lifters. One of these days we'll get that motor fired up.
I just feel like they run a bunch of part "X" for brand "Y" and then change the label set and run them for brand "Z". And, that for a lot of what we buy, not just car parts.
